配施矿物质有机肥及化肥减量对高原夏菜西芹产量的影响

Effects of Combined Application of Mineral Organic Fertilizer and Reduced Application of Chemical Fertilizer on Celery Yield

采用单因素试验设计,在大田栽培条件下研究了配施矿物质有机肥及化肥减量对西芹产量和品质的影响。试验结果表明,配施矿物质有机肥可以显著地提高西芹的产量和品质。在配施矿物质有机肥的条件下,化学肥料减少10%和20%时,西芹产量分别达到9 948.6,9 610.5 kg/667 m2。其中,在当地最佳施肥水平下减量20%并配施矿物质有机肥与当地最佳施肥水平处理的西芹产量没有显著性差异,表明在合理配施矿物质有机肥的条件下,将当前的化肥施用量降低20%以内在生产实践中是可行的。

We conducted the field trial to investigate the effects of combined application of mineral organic fertilizer and chemical fertilizer on the quality and yield of celery by using single factor test design. The results showed that, under the condition of combined application of mineral organic fertilizer, the quality and yield of celery were significantly improved, and the yields were 9 948.6, 9 610.5 kg/667 m2 when the application amounts were reduced by 10% and 20%. There was no significant difference between the yields of the local optimum chemical fertilizer treatment and the treatment reduced 20% chemical fertilizer with combined application of mineral organic fertilizer, indicating it was feasible to reduce the current optimum application amount of chemical fertilizers by 20% with combined application of mineral organic fertilizer reasonable.
